(2R)-2-Benzenesulfonamido-2-phenylethanoic acid: a new monoclinic polymorph
نویسندگان
چکیده
In the title compound, C(14)H(13)NO(4)S, a sulfonamide derivative of phenyl glycine, the aromatic rings are inclined at a dihedral angle of 28.03 (12)°. In the crystal, O-H⋯O hydrogen bonds link the molecules into chains propagating in [100] and a weak C-H⋯O interaction cross-links the chains in the c-axis direction. In the previously published polymorph, the dihedral angle between the aromatic rings is 45.52 (18)° and the structure is stabilized by three different types of ring motif.

(2R)-2-Benzenesulfonamido-2-phenylethanoic acid
In the title compound, C(14)H(13)NO(4)S, the dihedral angle between the aromatic ring planes is 45.52 (18)°. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds lead to chains of mol-ecules propagating in [100] in which the the ring motifs R(2) (1)(8), R(2) (2)(8) and R(3) (3)(11) are apparent. These polymeric chains are linked through C-H⋯O inter-actions.
متن کاملThe monoclinic polymorph of dimethylarsinic acid
The title compound, C(2)H(7)AsO(2) or [As(CH(3))(2)O(OH)], is an organic derivative of arsinic acid, and is also known by its trivial name cacodylic acid. In contrast to the first polymorph (triclinic, space group P[Formula: see text], Z = 2), the current study revealed monoclinic symmetry (space group C2/c, Z = 8) for the second polymorph. The configuration of the tetra-hedral mol-ecule shows ...
متن کاملSecond monoclinic polymorph of 4-[(1H-benzimidazol-1-yl)methyl]benzoic acid
Recently, we reported the first monoclinic [Kuai & Cheng (2011). Acta Cryst., E67, o2787] and the ortho-rhom-bic polymorph [Kuai & Cheng (2011). Acta Cryst., E67, o3014] of the title compound, C(15)H(12)N(2)O(2). Another monoclinic polymorph was obtained accidentally by the hydro-thermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413 K. The ...
متن کاملA new monoclinic polymorph of 1,1′-bis(diphenylthiophosphoryl)ferrocene
The title compound, [Fe(C17H14PS)2], is a second monoclinic polymorph (P21/c, with Z' = 1) of the previously reported monoclinic (C2/c, with Z' = 1/2) form [Fang et al. (1995 ▸). Polyhedron, 14, 2403-2409]. In the new form, the S atoms lie to the same side of the mol-ecule with the pseudo S-P⋯P-S torsion angle being -53.09 (3)°. By contrast to this almost syn disposition, in the C2/c polymorph,...
متن کاملMonoclinic polymorph of 2-(pyrimidin-2-ylsulfanyl)acetic acid
The title compound, C(6)H(6)N(2)O(2)S, is a new polymorphic form of 2-(pyrimidin-2-ylsulfan-yl)acetic acid. Unlike the previous orthorhombic polymorph [Pan & Chen (2009 ▶) Acta Cryst. E65, o652], the mol-ecules are not planar: the aromatic ring makes an angle of 80.67 (17)° with the carboxyl plane. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds into chains along [02].
